Is Imidazolidinyl Urea Vegan?
CautionSometimes. Imidazolidinyl urea (also known just as urea) is used to "brown" baked goods. It is usually synthetic, but if extracted from animals, it is excreted from urine and other bodily fluids.
Imidazolidinyl Urea and the Vegan Diet
Imidazolidinyl Urea is a compound primarily used as a preservative in cosmetics and personal care products to prevent microbial growth. It can also be used in food applications, particularly in baked goods to enhance browning. While it is typically synthesized for industrial use, it can originate from animal sources, specifically from urine and other bodily fluids, which may be a concern for vegans.
